Contact your dealer, and find out:
what embroidery file type your machine will use
maximum size of your embroidery field
How you transfer designs (probably from a thumb drive)
Go to Embroidery Library and set up an account. You select a design that will fit your hoop and then select the correct embroidery file type. When you make your purchase, you can download your file right away or just leave it in your account and download them after your class. The thing I really like about embroidery library is you can download any design you've purchased so if the hard drive on your PC crashes, you haven't lost your designs.
Wait until your class to verify, but I'm pretty sure you don't need software to just download and stitch out designs.
